I rode from Vientiane-Pakxan-Thathom-Muang Khoune-Phonsavan about 2 weeks ago,lots of road works between Pakxan and Thasi,didn't like that road much,even though the scenery wasn't too bad.Lots of dirt sections,lots of logging trucks.
But don't let that put you off though...it was an adventure!
After Thatom the road improved,with the odd crater here and there.

I just drove from Phonsavan to Paxsan 2 days ago. The road was mostly good, except for a 20 km or so stretch right after you take a right in Khonsana. It was pretty rough and washed out but my Cbr250 handled it ok.

The road works are basically still the same I understand.
20+ kms were they are cutting through the mountains.
In the wet some vehicles were stuck in there for a couple of days.
So you may want to check carefully in Pakxan /Phonsavan before taking off.
